Helicopsyche (Feropsyche) lara , new species

Fig. 55–61 View FIGURES 55 – 61 , 86 View FIGURE 86 .

Together with H. neblinensis , H. lara has a rounded, triangular gonocoxite which is unique among American Helicopsyche . Helicopsyche lara can be separated from H. neblinensis , in dorsal view, by a slightly wider tergum X having about 16 pairs of dorsal setae, and in lateral view, by the slightly more slender gonocoxite.

Male. Head: Antennal scape as long as eye diameter, with pale yellowish setae. Maxillary palp segments equally long, with dark brown and grey setae. Cephalic warts oval, about half as long as eye diameter; with yellowish setae, some dark brown near lateral margins. Forewing golden brown, length 5.1–5.4 mm. Sternum VI process ( Fig. 55, 56 View FIGURES 55 – 61 ) 1/ 3 its segment length, covered by microtrichiae; in lateral view ( Fig. 55 View FIGURES 55 – 61 ), nearly straight, slender along its length; in ventral view ( Fig. 49 View FIGURES 48 – 54 ), with proximal half slightly tapering, in distal half parallel­sided; apex bearing numerous ventral lamellae ( Fig. 56 View FIGURES 55 – 61 ).

Male genitalia ( Fig. 57–61 View FIGURES 55 – 61 ). Segment IX, in lateral view ( Fig. 57 View FIGURES 55 – 61 ), with anterior lobe triangular, oriented anteriad and located at midlaterally on segment; anterodorsal and anteroventral margins slightly concave; in dorsal view ( Fig. 58 View FIGURES 55 – 61 ), with inner margin widely ellipsoid; in ventral view ( Fig. 59 View FIGURES 55 – 61 ), with minute posterior process; lateral apodeme present as anteriorly oriented, nearly straight line ( Fig. 57 View FIGURES 55 – 61 ) reaching anterior margin; sub­marginal line absent; tergal transverse apodeme narrow; sternal transverse apodeme well developed. Segment X, in lateral view ( Fig. 57 View FIGURES 55 – 61 ), oriented posteroventrad, nearly straight; proximal half with dorsal and ventral margins parallel, distal half tapering toward rounded apex; in dorsal view ( Fig. 58 View FIGURES 55 – 61 ), slightly narrowing distally; apex without notch ( Fig. 58 View FIGURES 55 – 61 ); with about 16 pairs of about equally long megasetae in longitudinal group starting at midway on segment. Superior appendage ( Fig. 57 View FIGURES 55 – 61 ) club­shaped in lateral and dorsal views ( Fig. 57, 58 View FIGURES 55 – 61 ); curving posteriorly in dorsal view ( Fig. 58 View FIGURES 55 – 61 ). Primary branch of gonocoxite, in lateral view ( Fig. 57 View FIGURES 55 – 61 ), generally triangular, with undulate dorsal margin; apex rounded in lateral and dorsal views ( Fig. 57, 58 View FIGURES 55 – 61 ); central part of primary branch about as wide as height of central part of tergum X ( Fig. 57 View FIGURES 55 – 61 ); anterodorsal margin nearly straight, smooth; posteroventral margin nearly straight, undulated; basimesal lobe large, rectangular and protruding primary branch in lateral view ( Fig. 57 View FIGURES 55 – 61 ); in ventral view, cone­shaped ( Fig. 59 View FIGURES 55 – 61 ); with slightly undulating and diverging median margins armed with a strong seta; with about 8 short megasetae on apical margin; basal plate, in lateral view ( Fig. 57 View FIGURES 55 – 61 ), nearly straight, apex pointed; in ventral view ( Fig. 59 View FIGURES 55 – 61 ), strongly pointing anteriorly. Phallus, in lateral view ( Fig. 60 View FIGURES 55 – 61 ), gently bent ventrad at midlenth, dorsal margin nearly straight along its length; ventral margin gently concave; anterior 1/5 nearly 1.5x broader than its central part ( Fig. 60 View FIGURES 55 – 61 ); in ventral view ( Fig. 61 View FIGURES 55 – 61 ), tapering toward midlength; phallobase apparently absent; endotheca strongly produced ( Fig. 60 View FIGURES 55 – 61 ); sperm channel undivided; sclerotized posteroventral part narrow ( Fig. 60 View FIGURES 55 – 61 ), forming a truncate plate in ventral view ( Fig. 61 View FIGURES 55 – 61 ).

Holotype male: VENEZUELA: Lara : Parque Nacional Dinira, Quebrada Buenos Aires, 9°36.407'N, 70°04.178'W, 1850 m, 18–19.vi.2001, Holzenthal, Blahnik, Paprocki, & Cressa, ( UMSP 000074735) ( UMSP, pinned).
